The circular, independent needle, type isprie ma'rily intended for truerib knitting. Since such knitting is accomplished through thecooperation of needles working simultaneously in both cylinders withoutthe aid of sinkers or other similar devices for insuring that the loopsare properly cast off, some means for maintaining tension uponth'e'fab'ric is es's'ehtial to insure that casting off willbe'ac'com'plished effectively.

In the drawing:

Fig. 1 is a general view of the mechanism for producing wrap patternsand also of the means for applying tension to the fabric through theheel and toe pocket; M

Fig. 2 is a view of a part of the means for operating the wrapmechanism;

Fig. 3 is a view primarily illustrating the means through which theseparts and the heel and toe pocket spreader are operated;

Fig. 4 is a view illustrating particularly the heel and toe pocketspreader and the device for applying tension to the fabric immediatelyfollowing these parts independently of the regular fabric tension; and

Fig. 5 is an elevation partly in section illustrating this tensioningdevice and also showing the position of the wrap spindle with respect toit and to the cylinders.

Generally speaking, any suitable type of fabric take-up may be employedfor this purpose. However, the knitting of the heel and toe pocketsintroduces unsymmetrical portions of fabric which completely eliminatethe possibility of uniform tension being applied to the fabricimmediately succeeding them by the usual fabric take-up means.Consequently, a supplementary take-up device should be used to applytension to the heel and toe pockets so that the immediately succeedingfabric may be properly tensioned at all points.

A form of supplementary take-up of this character is shown in Figs. 1, 4and 5. It consists of a disc-like pocket spreader 8| mounted on the endof a rod 82 extending from the uppermost part of the machine throughtubular shafts 83 and 84 within housing 85. Normally rod 82 ismaintained in its uppermost position, that shown in Fig. 1, by a spring86. In this position, spreader 8| is inoperative.

Associated therewith is the supplementary fabric take-up proper 81(Figs. 4 and 5). This consists of a ring 88 longitudinally movablewithin thelower cylinder I, provided with inwardly pro- 7 Claims. (01.ct -150) 2 jetting needle-nee points s adapted to ngage with the fabricof the heel or toe pocket. Ring 88 is mounted on area 90 by which it ismoved up and down by suitable mechanism- In spreader 8| are V shapedrecesses SIfad'apted to register withpoint's 89 as shown in Fig. 4.

Registry is maintained. through a pin 92 (Figs. 2 and 3) mounted in aring 93 (Figs; 2 and 3) vertically 's'lidable on housing 85 andprojecting through a slot in this'housing so as to engage a recess 94 inrod 82. This recess is of sufficient length to permit rod 82 to move upand down the required distance but will prevent it from turningindependently of housing 85. Spreader 8| and supplementary take-up 81rotate with the cylinders, consequently, their relative positions inthis respect are constant.

When the heel pocket is completed rod 82 is caused to move downwardagainst spring 86 by suitably timed operating means, indicated in Fig.

1 by the lever 95, to engage spreader 8| with it. This spreads thepocket 96 substantially as shown in Fig. 5. Thereupon supplementaryfabric take-up 81 moves up from a low position, passes along the outsideof toe pocket 96 to substantially the position shownin Fig. 5, thepoints 89 penetrating the fabric of the toe pocket. Then spreader 8| ispermitted to move upward again to its inoperative position and take-up81 is released to descend of its own weight, supplemented by a spring,if desired, as the subsequent knitting progresses and maintainingtension upon the fabric above the toe pocket.

When the supplementary take-up has reached a low position it isreleased, the tension then being maintained by the regular fabrictake-up. After the toe pocket is completed the same procedure isrepeated to maintain tension on this side of the fabric subsequentlyknitted.

During both of these operations the rest of the fabric such as that ofthe leg passes through the arcuate slit 91 forming an extension oftake-up 81 on the side opposite points 89. This fabric is tensionedthroughout by the regular fabric takeup. Through the cooperation of theregular and auxiliary take-ups an adequately uniform tension ismaintained on the fabric at all points to insure perfect knitting.

The auxiliary take-up just described is a modification of that shown inU. S. Patent #2,068,605 to which reference may be had for a moredetailed description of its general characteristics and mode ofoperation. Except for the heel spreader 8| and its operating mechanismthe take-up may be considered as substantially identical in constructionand in operation to that of this patent. Attention is called to claims3, 4 and 8 of the patent referred to which are believed to cover broadlythe supplementary take-up of this invention.
